1 Claim. (01. 231-21) This invention relates to methods of assembling and binding sheets of paper, carbon paper, manifold copies with carbon inserts, and the like, and is primarily intended to provide manifold 5 carbon copy assemblies for use in mechanical duplicating machines, such as typewriters and the like.

One of the objects of the invention is to produce an assembly of copies and carbons so made 10 that the edge by which it is fed to the platen of a typewriter or the like, is rounded, smooth and of one piece, the edges of all of the inserts being enclosed wi sheet of any desired thickness, and being .secured 15 therein without the use of any metal parts which frequently lead to the injury of rubber platens and feeding rollers.

. Another object of the invention is to produce an assembly of this character in which either 20 single or a multiplicity of copies may be produced simultaneously with the production of the original.

A further object of the invention is to produce a construction. which peculiarly lends itself to use with what is called one-time carbon, the carbon sheets being slightly shorter than the original and copy inserts, so that when the material is removed from the machine, the original and copies may be separated from the binding I 30 edge and from each other and the carbon removed, all as the result of a single operation.

With the general objects named in view and others as will hereinafter appear the invention consists in certain novel and useful process of 35 production and in the finished article as will hereinafter appear; and in order that the invention may be fully understood, reference is to be had to the accompanying drawing, in which:

40 Figure 1 is a. broken perspective view of av manifold carbon insert form, embodying the invention.

Figure 2 is a section on the line II-II of Figure 1, but leaving the carbon sheets unsec 45 tioned in the interest 'of cleamess.

. 50 type of U-shaped binder construction. a

Figure 5 is a broken perspective view of the invention as it may appear when an original and a single carbon'copy are all that is required.

The drawing, where like reference characters 5 identify corresponding parts in all of the figures,

in a U-shaped binder or cover is to be understood as being illustrative and not restrictive in its character, as the invention is considered to lie in the method of making it possible for the hand or machine assembly of inserts in a binder having its folded portion arranged 5 for the penetration of adhesive, and finally in the application of adhesive to such prepared folded edge of the binder. By this method of operation, .it. is apparent that the manifoldcopies may be assembled by hand or by a ma-- chine of very simple construction, ,since application of glue to the inside face of a binding stripwould make the assembly dimcult and l messy if conducted by hand, or would require a complicated and expensive 'machine, if done mechanical1y."The binder or edge protector is of U-shape and may or may not, as desired, be long enough to. provide an' original and one carbon copy.

In Figures 1 and 2 of the drawing, I and 2 respectively indicate the original and the final copy sheets of a manifold assembly, said sheets being the binder or cover thus provided, with their upper margins adjacent the prepared folded edge, are a pair of carbons 4 and a copy insert 5, it being understood, however, that any number of carbons and inserts maybe positioned within the binder, only as limited by the capacity of the duplicating machine or typewriter. After the parts have been assembled, any suitable adhesive is applied externally to the prepared edge of the binder, and this adhesive will penetrate through the openings 3 (see Figure 2), and will adhere to and secure all of the inserts and carbons in fixed relation to the binder. In actual practice, when the adhesive is applied by hand, it

has been found desirable to stack a number of the manifold copies as thus assembled and to place them under pressure. Their binding edges may then be brushed indiscriminately with the glue, and the compression of the members is found to prevent entry of the glue between the sheets, such glue being limited-to filling the openings in the folded edge of the binders and to filling the microscopic space between the ends of the inserts and the inner face of the binders as greatly magnified at 6 in Figure 2. Where onetime carbon is used in the making .of a plurality of copies, the work of separating the sheets from i the carbons is speeded up and facilitated, by providing each of the sheets with a line of spaced tear slots or perforations I. With a manifold copy prepared in this manner, the operator can grasp the binding edge in one hand and the projecting ends of the sheets in the other, and with a single quick jerk can pull all of the sheets from the binding edge, withdrawing the carbons, which need not be slit or punched, and thus will remain secured to the binding edge.

In Figure 3, a slightly different method of assembling the manifold is shown, the copy inserts being of saddle-back type as shown at 9, and

being provided with a perforated edge 10, the three carbon sheets i I being of single sheet character and inserted above each of the copy sheets. 3f course, if desired, the carbon inserts may be of saddle-back construction for quickness and ease of assembly. In Figure 4, another type of construction, in which the binding edge or binder has a full back sheet I2 to provide a carbon copy, while the front sheet is short as shown at E3, so that the original l3a may be a separate sheet, if desired. The openings to receive the adhesive in this construction are shown as of elongated shape as at I4.

When the assembly is to be used for billing forms, for example, to provide an original and one copy, the type of construction shown in Figure 5 may be found desirable, comprising a saddle-back sheet providing an original IS, an -"nserted carbon sheet l6, and a copy sheet IT. The fold line of the sheet is provided with a series of spaced slits l8. When a stack of manifold sheets of this type are assembled and placed under compression with their folded edges in alinement, it will be found that the pressure causes the slits to gape slightly to admit entry of the adhesive into the pocket or cavity l9, magnified in the figures, to secure the inserted carbon sheets in proper position. With this type of i construction it will be apparent that the operation of separating the back and front sheets along the line of the slit l8 will simultaneously release the enclosed carbon sheets.

From the above description, it will be apparent that while I have described what now appears to be the preferred construction and method of making, it is to be understood that I reserve the right to all changes within the spirit of the invention and without the ambit of the prior art.

I claim:- I

The process of binding a plurality of sheets which comprises inserting one margin of said sheets between the legs of a U-shaped binder having its folded edge arranged with a series of spaced slits, until the edges of said sheets are in close proximity to the folded portion thereof, compressing the binder and inserted sheets to effect gapping of the side edges of said slits, and finally in applying an adhesive to the line of gapping slits for penetration into the binder to secure the inserted sheets in position.
